Wildfire hazard zones in San Francisco County

CAL FIRE's statewide map records no Fire Hazard Severity Zone anywhere in San Francisco County. That is unusual, and it does not mean an insurer will treat every address here as low risk — carriers price on their own wildfire models as well as the state map.

Check your own address anyway. Zone boundaries are drawn at a scale that does not follow parcel lines, your flood zone is a separate question, and the eleven Safer from Wildfires measures earn a discount under California law regardless of which zone you are in.

These are the classes that occur somewhere in the county, not a measure of how much of it they cover. The state service returns whole zone polygons that intersect the county boundary rather than polygons clipped to it, so any share-of-area figure derived from it would overcount. We would rather publish nothing than a number we cannot stand behind.

Check a specific address

Zone boundaries do not follow parcel lines, so the county answer is not the property answer. This returns the Fire Hazard Severity Zone and FEMA flood zone for one address, read live from the state and federal services.

What the zone changes

CAL FIRE maps describe hazard. Insurers use their own risk models and eligibility requirements; the map does not decide coverage or price. It describes the land rather than the house: a well-prepared home and a neglected one on the same street sit in the same zone. What separates them, in an insurer's eyes, is documented mitigation — the Safer from Wildfires measures California requires insurers to recognise, and the evidence that the work was actually done.
